The optimal ratio is obtained, and then the wood chip biomass fuel has the best performance, high use value and good application prospect.

The invention discloses a combustion-supporting device of a furnace, which comprises a furnace body and a chimney, wherein the chimney is arranged on the furnace body; a combustion chamber is arranged in the furnace body; one side of the combustion chamber is provided with a furnace door; and the lower end of the combustion chamber is provided with an air intake. The combustion-supporting device is characterized in that a water storage layer is arranged around the combustion chamber; a steam chamber is arranged above the water storage layer; the steam chamber is connected with a steam pipe; afurnace bar made of hollow pipes is arranged between the air intake and the combustion chamber; the furnace bar is communicated with the steam chamber by the steam pipe; and an injector head is arranged above the furnace bar. The invention has the advantages that the furnace bar made of the hollow pipes is arranged between the air intake and the combustion chamber, and the injector head is arranged above the furnace bar, and therefore, steam can be sprayed into the combustion chamber to agitate air in the combustion chamber, thereby taking the combustion-supporting effect and greatly saving fuels.

The invention relates to a manufacturing process for producing a microcrystal foaming fireproof thermal insulation material by utilizing aeolian sand and peat, and in particular to a manufacturing process of a fireproof thermal insulation material by reutilizing Mu Us aeolian sand in Ningxia region. The manufacturing process is characterized by comprising the following steps: processing aeolian sand, peat and limestone into tiny fine powder, uniformly mixing the fine powder according to a specified proportion, flattening and ramming the fine powder mixture in a firing mould, integrally firing the mixture in a high-temperature firing kiln once and cooling molding. The manufacturing process for producing the microcrystal foaming fireproof thermal insulation material by utilizing the aeolian sand and the peat has the beneficial effects that, by utilizing the aeolian sand as a main raw material, the environment pollution problem caused by the aeolian sand is solved, the production cost is reduced, the resource utilization rate is increased, the waste is changed into the wealth, and the environment is optimized; by utilizing the peat as a production raw material, a combustion supporting effect of raw material self combustion in a firing procedure is realized, the firing speed can be increased, and the fuel cost and the energy consumption are reduced.

The utility model relates to a smoldering device for fast and low-temperature combustion of carbon powder in a biomass briquette fuel combustion device, which belongs to the technical field of biomass combustion. It is characterized in that: the two ends of the air inlet pipe (27) communicate with the outside of the smoldering pool (20) respectively, the wall of the air inlet pipe (27) is provided with air outlet holes, and the air inlet pipe (27) is filled with flowing air , so as to cool the smoldering pool (20), part of the air in the air inlet pipe (27) enters the smoldering pool (20) to support combustion, and the air inlet pipe (27) is also connected to an air volume adjustment unit that adjusts the cooling air flow rate, and the combustion-supporting adjustment The mechanism is connected with the air inlet pipe (27), and cooperates with the air volume adjustment unit to adjust the amount of combustion-supporting air entering the smoldering pool (20).
